Where Is the Battery In a BMW?
A BMW sedan or SUV has a battery underneath the hood. But this German manufacturer keeps on flooding the market with fancier and classy cars with different designs.
These different engineering designs pose a challenge for first-time owners to locate the battery. The latest models have the battery located in the boot or trunk as opposed to other types of automobiles.
These batteries are usually in the boot compartment on the right-hand side. The location helps prevent the engine from damaging the car battery in the long run.
Many first-time BMW owners find it a challenge to locate the battery. Some people even assume the modern BMW models do not have batteries since the area is well-covered. We recommend reading the BMW manual to save time and money.
Locating the car battery will reduce the hassle of replacing it whenever a need arises. Besides that, it will make the replacement task straightforward. You will only need to turn the switch on the little tray on the right-hand side of the trunk to unlock the panel.
Signs that the BMW Battery Is Failing
The car battery location in the trunk makes it easy for BMW owners to forget and ignore its existence. The quest to locate the battery occurs when the vehicle encounters issues that require battery inspection.
I recommend locating your BMW battery in advance to avoid the searching hassle due to a problem. Besides that, develop the habit of inspecting the car battery to prevent damaging the cells or any signs of cracks.
Below are the signs in your BMW that show the battery is failing:
Dashboard Warning Signs
Modern BMW models have dashboard warning signs that tell the owners whenever the vehicle has a component problem. The battery warning sign will appear when the car battery has some issues.
I recommend not ignoring the warning sign since it could lead to severe damage.
BMW with Dim Headlights
Most BMW trims come with bright headlights. A faulty car battery will make the headlights go dim or fade over time. A dim headlight is an indication that the car battery is not providing adequate power.
The golden rule is to inspect the battery and see if there is a need to replace it.
BMW Won’t Start
If your BMW is failing to start, it is an issue related to the faulty battery. The battery does not provide adequate electric power to ignite the vehicle. We recommend checking the battery first before starting the car.
Battery Not Holding Charge
Most BMW battery models can carry the energy without depending on the alternators. But the capacity keeps on reducing as the battery gets old or experiences some damage. If the car battery cannot run the stereo while resting, you need to replace it.
